Alumina stands out as a highly prevalent ceramic material in contemporary applications. Serving as a prime illustration of an electrical insulator, alumina boasts superior temperature resistance, chemical stability, and enhanced thermal conductivity. Its useful effectiveness spans extends to various sectors including medicine, industry, household products, as well as the manufacturing of electrical components and batteries. Considering these important applications, this study develops a mathematical framework to analyze MHD mixed convective three-dimensional nanofluid flow incorporating alumina nanoparticles over an extending surface. Initial assumptions constrain the nanofluid flow to exhibit rotation. A significant aspect of this study revolves around examining the impact of nanoparticle size and nanolayer characteristics on the nanofluid and highlighting its innovative contribution. The modeled equations have been evaluated numerically by using bvp4c MATLAB command. It is concluded that the higher magnetic factor augments the thermal distribution and secondary velocity distribution while retards the primary velocity distribution. Upsurge in rotation factor has augmenting impact on thermal distribution while it has retarding impacts on primary and secondary velocity distributions. Escalation in empirical factor causes augmentation in the primary velocity and temperature distributions while it retards the secondary velocity distribution. It is also noticed that growth in Nusselt number is greater in case of escalation of nanolayer in comparison of upsurge in nanoparticles' diameter. The results of this work have also been confirmed with available results in the literature through a comparative analysis.

Container Aedes mosquitoes are the most important vectors of human arboviruses (i.e., dengue, chikungunya, Zika, or yellow fever). Invasive and native container Aedes spp. potentially utilize natural and artificial containers in specific environments for oviposition. Several container Aedes spp. display ‘skip-oviposition’ behavior, which describes the distribution of eggs among multiple containers during a single gonotrophic cycle. In this study, we compared individual skip-oviposition behavior using identical eight-cup testing arenas with three container Aedes species: Aedes aegypti (Linnaeus), Aedes albopictus (Skuse), and Aedes triseriatus (Say). We applied the index of dispersion, an aggregation statistic, to individual mosquitoes’ oviposition patterns to assess skip-oviposition behavior. Aedes aegypti and Ae. albopictus utilized more cups and distributed eggs more evenly among cups than Ae. triseriatus under nutritionally enriched oviposition media (oak leaf infusion) conditions. When presented with a nutritionally unenriched (tap water) oviposition media, both Ae. aegypti and Ae. albopictus increased egg spreading behavior. Aedes albopictus did not modify skip-oviposition behavior when reared and assessed under fall-like environmental conditions, which induce diapause egg production. This study indicates specific oviposition site conditions influence skip-oviposition behavior with ‘preferred’ sites receiving higher amounts of eggs from any given individual and ‘non-preferred’ sites receive a limited contribution of eggs. A further understanding of skip-oviposition behavior is needed to make the best use of autodissemination trap technology in which skip-ovipositing females spread a potent larvicide among oviposition sites within the environment.

The emergence of new display technologies can change the perception of product design features and their assessment. Previous studies are limited to comparisons between a few technologies; the real product is considered only occasionally. This work compares the perceptions of 10 design features in two household products, shown by five display technologies (image rendering, 360° rotation, and augmented, immersive, and non-immersive virtual reality), and also with the real product. Results show that the 360° rotation provides the best perception for the most important features. However, the perception of aesthetic features is better achieved with i_VR. Other global results vary depending on the product. Finally, interaction with the real product shows a quite different perception for many features. The results contribute to the understanding of product perceptions influenced by different displays, comparing them with perceptions generated through real interaction. It is expected that the conclusions will be used to optimize the presentation of product features.

The frequencies of use for each codon are not equal, some of them occur more often (frequent codons), whereas others rarely (rare codons). Since in E. coli the most frequent codons are decoded by the most abundant tRNAs, this codon usage is considered to correlate with the availability of some tRNAs, the most limiting step in translation elongation (Ikemura, ). [...]codon metrics based on codon frequency have been used for optimization of poor genes with low expression. The T7 RNA polymerase is much faster than E. coli RNA polymerase; these kinetic differences limit the coupling of the translation with the transcription. [...]T7 RNA polymerase activity results in a mass production of mRNA, that is not protected by transcribing ribosomes, which occurs normally with the E. coli RNA polymerase (Iost and Dreyfus, ). Proteins with disulphide bonds are difficult to express because bacterial cytoplasm is typically not suitable for sulphide bond formation; however, E. coli strains have been successfully engineered to oxidize cysteines in the cytoplasm (Anton et al., ). [...]there are now E. coli strains that can perform post‐translational modifications like N‐glycolyzation, a modification generally occurring only in eukaryotic cells (Wacker et al., ) or acetylation (Johnson et al., ).

Cricotopus lebetis Sublette (Diptera: Chironomidae) is an aquatic insect adventive in Florida. Evidence from previous studies suggest the insect may have value as an augmentative biological control agent for hydrilla, Hydrilla verticillata (L.f.) Royle (Hydrocharitaceae), but there are gaps in knowledge of the biology and life history traits. To increase understanding of this insect, this study was comprised of 3 experiments. In the first experiment, we investigated the productivity and survival rate of C. lebetis across 6 generations by analyzing our colony data. Then the effect of intraspecific competition on the rates of pupal and adult eclosion was studied by monitoring hydrilla tips in test tubes with varying numbers of larvae. Finally, the level of hydrilla stem tip damage caused by a C. lebetis larva was determined by monitoring tip damage following feeding of a known number of larvae on a standardized number of hydrilla tips. The first experiment revealed the average survival rate of C. lebetis from egg to adult was 16.4%. Approximately a third of the females (30.2%) oviposited. The egg masses had an average of 154.5 eggs per egg mass and an 83.7% fertility rate. Investigation of intraspecific competition revealed pupation and adult eclosion was highest with 1 C. lebetis larva per hydrilla stem tip. Evaluation of the impact of C. lebetis larvae feeding on hydrilla showed stem tips in treatments with C. lebetis larvae experienced 38% higher damage compared to stem tips in control treatments. Overall, this study provided valuable information useful in improving the mass rearing of C. lebetis and predicting the damage caused by C. lebetis. For example, for efficient mass rearing, an average of 1 larva per hydrilla tip should be maintained with the remainder of eggs being used for augmentative releases.
